Application filed December 11, 1920 Serial No. 429,840.

chines of the continuous billing variety, one a form of which isdescribed in the patentto Wernery & Smith, No. 1,132,055, in which thetypewriter carriage comprises an exbon-paper carriage adapted to carrycarbon-sheets for the reproduction in carbon copies of matter typed uponan outer sheet.

In machines of the Wernery & Smith type, the carbon-sheets are usuallyof lim .ited length which are clipped to clip-bars u on the carbon-pa rcarriage. When any s eet is worn out thz clip is released and a newsheet clipped in place of the exhausted one, which is removed. Thepresent invention rovides a continuous carbon-paper supp y. The carbonpapers are cross-folded in the form of webs and stored in containers ormagazines located between the continuous work-sheets.

Means are provided whereby a fixed portion of the Carbon-paper web isclamped in position, and no new portion of the web is taken fromthemagazine unless desired. At such times the clamps are releasedand a newportion of carbon-paper, drawn ofi' whereupon the I clamps are restored.

Other features and, advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a perspective view of a carhon-paper magazme.

Figure 2 is aside view, largely sectioned, of an Underwood continuousbilling machine with the new carbon-paper supply mechanism mounted on acarbon-paper carriage, and showing the carbon-papers clamped againstwithdrawal from their magazines.

Figure 3 1s a view of a portion of the apof which the following is apaper carriage with the magazines removed. Figure 5 is a plan view ofthe device shown in Figure 2. In the-usual Underwood continuous billmgmachine, continuous work-webs 1, 2, 3 and 4 are led down over a rearpaper-table 5, forming part of the typewriter carriage 6, and-are'heldagainst the platen 7 by the usual rear and front feed-rolls 8 and 9.

The webs are interleaved with carbonsheets 11, 12 and 13, which normallyextend as far as'the printing line, and, from that line, the webs andcarbon-sheets, in the operation of typing, pass above the usual frontknife 15 and lie upon a front paper-table 16. When a form on webs 1, 2,3 and 4 is fully typed, the platen is swung up in its swing frame 17 byrotating the frame about the front shaft 18 by means of a gage member21. The frame is normally held in position, shown in Figure 2, byaspring catch 19" engaging a pin 17 on the frame, from which it may bereleased by handle 19. The platen is swung upwardly a distance such thatthe various sheets around the platen may be drawn out to formsubstantially a continuous straight line with the sheets as fed from therear (see patent to Wernery & Smith, noted above). .The straightening ofthe sheets makes it possible to retract the carbon-sheets without unduefriction being created by the webs, which would be the case if the websfollowed 'a Curved path. The

various sheets are gaged against agage 20 adjustably mounted on theusual gage mem 'ber 21. The webs are held in the gaged posit-on whilethe carbon-sheets are pulled handle22 to carry rearwardly thecarbonpaper carriage 23. The carriage travels on side rails 24:connected at the rear. by a cross-bar 25 to form a rear extension of thetypewriter carriage 6. Usually there is provided a stop 26, which servesto arrest the carbon-paper carriage when the latter is pushed r'arwardlyby the handle 22. v

According to the present invention, the carbon-sheets, instead of beingshort sheets, as is customarily the case are in the form of webs 30 ofconsiderable length, these webs supplying the carbon-sheets 11, 12 and13. The webs 30 are housed within boxes or magazines 31 of any suitableconstruction,

and here shown as in the form of flat boxes provided with slidablecovers 32. The boxes rest flatwise one above the other, in verticalalignment, and in order to provide a space between the top of one boxand the bottom of the box above to allow the continuous work-webs topass through, the side members 33 of each box, at the ends of the box,.

project slightly below the bottom of the box as at 34. 1

The boxes 31 are positioned on the movable carbon-paper carriage betweenside walls 40 fixed to a base 41 provided with rollers 42 operating onthe side rails 24.

- walls 40. The boxes are therefore confined between the side walls, thebent ends 44 at the rear edges of the side walls, and the frontcross-bars 45. The side walls are cut out, as shownin Figures 2 and 3,to allow access to the boxes, when it is desired to remove them from thecarriage.

A forward extension 50 is formed integral with each side member 40, andhas fixed to the inner surface thereof lower jaws 51 of a carbon-paperclamping device. Said jaws 51 are provided with flanges 52 adjacent theextensions 50. Adapted to fit between the side members and enclose saidlower jaws is a vertically reciprocable slidable frame composed of sidemembers 60 and upper jaws 65. The width of said frame member issubstantially equal to ,the distance between the inner surfaces-of theside members 40 so that there is very little lateral play. The sidemembers are formed with openings 62 just large enough to permit thelower jaws 51 to pass therein. Openings 62-lead to larger cut-outportions 63 of substantially the same width as the jaws 51, so that oncesaid jaws are housed within sa1d cut-out portions, members 60 areconstrained to move in a vertical direction. Adjacent the upper ends ofthe cut-out portions are fixed to the side members 60, upper jaws 65having flanges fixed to the members 60 at 61 and co-operating withthelower jaws 51. The fixed jaws 51 form a lower set of jaws and themovable jaws 65 form an upper set of jaws, of which each lower jaw 51and its co-o-perating upper jaw 65 form a pair of relatively movableclamping jaws. A spring 70, connected-to a pin 71 on the side member 40and to the upper part of side member 60, is provided at each side tokeep member 60 in lowered position, so

that upper jaws 65 will be pressed normally against lower jaws 51. Thecarbon-webs pass through openings in the upper portion of the boxes, andbetween the upper and lower jaws to the platen. When the jaws are inclosed position, the carbon-papers are grippedand clamped in position,and unwinding of the carbon-webs is prevented.

When the portions of the carbon-papers being used are exhausted, and itis desired to withdraw fresh portions from the carbon-webs, means areprovided for separating the upper and lower jaws of the clamps to permitsuch withdrawal. Said means comprises cams 80 mounted beneath sidemembers 60 and fixed to a shaft 81 journaled in the extensions 50 ofside members 40. The shaft is provided at one end outside the sidemember with a handle 82. When the handle is in the Figure 2 position,the upper jaws are in lowered position, and the clamp is effective toprevent withdrawal of. fresh carbon-paper. When the handle is rotatedrearwardly to the Figure 3 position, the side members 60 are raised bythe cams 80 and the upper jaws are separated from the lower jaws topermit unwinding of carbon-paper from the carbon webs. A two-way springfixed to a pin 85 on extension and a second pin 86 on handle 82 willhold the handle in the Figure 2 or Figure 3 position, according as thespring lies to one side or the other of the axis of shaft 81.

In the operation of the device, therefore, assume the parts of themachine. and the various sheets tobe in the position shown in Figure 2.As the forms on webs 1, 2, 3

and 4 are typed, the webs and their carbon-,

sheets will be advanced around the platen, drawing the carbon-papercarriage forwardly along rails 24. When the forms have been fully typed,the platen is swung upwardly carrying the gage 20 forwardly. The formsand carbon-sheets are then drawn forwardly and gaged against the gage20-. Only the webs are held together while the handle 22 is pushedrearwardly, and the carbon-paper carriage moves back drawing thecarbon-sheets with it. lVhen the used portions of the carbon-sheetsbecome worn and it is desired to substitute new portions, the webs andcarbon-sheets are again gaged by the gage 20, but instead of holdingonly the webs, the webs and carbon-sheets are held. Handle 82 is thenswung rearwardly to the Figure 3 position raising members and henceupper jaws of the clamps, thus releasing the carbon-sheets. Handle 22 isagain pushed rearwardly, but since the carbonsheets are held at gage 20,the carbon-webs in the boxes 31 will be drawn off. When the carbon-papercarriage reaches its rearmost point, handle 82 is swung forwardly to theFigure 2 position to clamp the carbon-sheets in the new position, andthe typed forms and the worn carbon-sheet portions are then torn ofi'together against the knife 15. v
